ROTARY ENGINE.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed June 23, 1908. Serial No. 439,929.

To all whom it ma/y concern:

Be it known that I, CARLTON C. HOLLO- wAY, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Rotary Engines, of whichthe 'following is a specification.

This invention relates to a rotary motor or engine particularly devisedto fully and economically utilize the driving energy of a motive agentwhich may be either a iiuid or liquid of suitable nature applied to thedriving elements to the best advantage to continuously and effectively.rotate a power shaft actuated by the driving elements as a unit withoutlost motion. n

The principle involved in this motor is the direct action of the motiveagent on movable driving elements fixed to a ower transmit.- ting shaftand the cooperation therewith of temporarily fixed elements which atintervals are moved, subsequent to the movement of the driving elements,with the motor cylinder to continuously form new motive agent receivingpockets regularly and consecutively occupying new positions within theinclosure. The pockets in their cycle rapidly move and receive themotive agent without the least fluctuation and all simultaneouslyreceive uniform charges of the motive agent with obvious advantages inovercoming the obstructive influence of dead center", and in materiallyreducing wear of the moving parts as well as insuring an effective andpositive application of the motive agent. The motor is also equippedwith rapid exhaust means so that no back pressure counteracts theregular rotation of the power generating elements.

Specifically the invention contemplates the association of coperatingmechanical devices contributing to the practical operation of the motorand which will be more fully hereinafter specified in preferred form,but subject to such modifications as fairly fall within the scope of theinvention.

In the drawings Figure I is a side elevation of a rotary motor or enginebroken away in parts and embodying the features of the invention. Fig.II is a longitudinal vertical section of the motor. Fig. III is atransverse vertical section. Fig. IV is an end elevation looking towardthe motive agent inlet extremity, and Fig. V is an end elevation lookingtoward the extremity opposite that shown by Fig. IV.

Similar reference characters are used to designate corresponding partsin the several views.

The numeral 1 designates a suitable base fixedly supporting a tubularinclosure 2 having heads 3 and 4 preferably tied by rods 5 engagingbosses 6 on the heads and arranged at intervals around the inclosure.INithin the inclosure 2 a cylinder 7 is rotatably mounted, and extendingcentrally through the heads is a power shaft 8 concentrically disposedwith relation to the inclosure and cylinder, and provided with suitablestuffing boxes 9 and 10, secured to the heads 3 and 4, to obstructleakage. Exteriorly of the heads 3 and 4 the shaft is supported bysuitable pillars or uprights 11 rising from the base 1. At all pointslubricating devices adapted for the purpose will be provided.

Freely movable within the cylinder 7 and. secured to the shaft 8 are aplurality of driving elements in the form of flat radial wings 12constituting the direct actuating means for the said shaft and shown forthe purpose of practical illustration in the present instance as four innumber. This number, however, may be varied in proportion to thedimensions of the motor The radial wings 12 are secured to the shaft 8through the medium of a hub 13 directly keyed to said shaft and havetheir inner edges for about one-half their length recessed as at 14 tofreely move around a sleeve 15, loose on the shaft 8 and carrying radialpocket closers 16, secured at their outer edges to the cylinder 7, andmovable with the latter. These closers 16 form movable walls orpartitions and have their inner edges recessed as at 17 for aboutonehalf their length, and reversely with relation to the recesses 14 ofthe wings 12 to freely move around the hub 13. The wings 12 and closersor Walls 16 at their outer portions beyond the hub 13 and sleeve 15extend fully from the inner surface of the head 3 to the correspondingsurface of the head 4, and the inner and outer, as well as the end edgesthereof, moving in contiguous relation to the parts specified, areprovided with packing strips o any preferred form as at 18.

The wings 12 and closers or walls 16 are normally held in close relationas shown by Fig. III, to form pockets, and at regular intervals in thehead 2, ingress ports 19 are formed and communicate with said ockets.Adjacent to the pockets and norma y in the rear of the closers or walls16 are radially arranged series of exhaust ports or openings 20 whichoutlet in any suitable escape conduit means, the said exhaust openingsextending almost fully from the cylinder 7 to the hub 13 and sleeve 15and are also formed in the head 2.

Cooperating with the ingress or feed ports 19 are a plurality of plugvalves 21, one valve to each port, and controlling the open and l0closed condition of the feed pipe coupling members 22 and thesimultaneous supply and cutoff of the motive agent to and from theseveral pockets formed by the Wings 12 and closers or walls 16. Thestems 23 ofthe valves 21 project outwardly and are engaged by slottedheads or keys 24 which project therefrom and have shifting levers 25movably secured to their inner ends. The shifting levers 25 areintermediately fulcrumed as at 2O 26 and also movably attached to tappetlevers 27 projected inwardly and also intermediately fulcrumed as at 28.The levers are attached to the levers 27 between the outer ends of thelatter and the fulcrums 28, 25 and to the outer ends of the said levers27, retractible springs 29 are secured and also attached to adjacentportions of the head 2 or the valve 30. The inner ends of the tappetlevers 27 are located at the same distance 30 from the axis of the motorfor simultaneous engagement with the four teeth 31 ola tap et wheel ordisk 32 carried by and rotata le with the shaft '8. This valve mechanismis so timed as to operate to opening the valves 21 just after theseveral pockets have been completed by the movement of the closers orwallsv 16 and instantaneously subsequent to the exhaust of the motiveagent through the exhaust ports or openings 20, and which exhaust willbe effected as soon as each wing 12 passes over said ports or openings20.

',lhe cylinder 7 is regularly rotated or moved around the wings 12 by atimed mechanism yhaving an interval operation previous to the inlet ofthe motive agent into the pockets. This mechanism involves a ring 33rotatably mounted on the exterior extremity of the sleeve 15, whichprojects through the head 3 on the inclosure, the said ring being freelyrotatable on the hub and carrying a plurality of dogs 34 on its innerside, which are normally in engagement with the notches 35 in the'adjacent portion of the said sleeve. Close to ring 33 an oscillatinglever 36 is fulcrum'ed on an upright 37, rising from the base 1, theupper extremity 38 of said oscillating lever movably projecting abovethe upper end of the upright and carrying a roller 39. The oppositeextremity 40 of the lever is curved and extends below the lane of thering 33 and has the lower end orP a pull lever 41 movably attachedthereto, the upper end of the latter lever being secured to the ring 33.

The oscillating lever 40 together with the lever 41 and the ring 33 anddogs 34 constitute actuating means for the sleeve 20 carrying theclosers or walls 16and shifting the latter in timed relation to themovement of the wings 12, so as to consecutively and regularly completethe pockets for receiving the motive agent and utilizing the energythereof. The actuating means for the sleeve 15,

as just explained, is controlled as to its movement by a flanged ilywheel 42 which may be pro erly termed the controller, the llange 43 75of t e said ily wheel being disposed in concentric relation to the shaft8 and is keyed to the latter, and consequently is regularly rotated bythe said shaft in consonance with the movement of the wings 12. Theflange 43 is formed at intervals with cam projections 44 which extendinwardly and which are formed with a long inclined edge 45 and a shorteredge 46 approximately at right angle to the edge 45 and continue intothe latter by 85 a rounded or curved apex 47. The edge 45 of each camprojection is engaged by the roller 39 on the upper end of theoscillatingl lever 36, said edge of each cam projection constituting themeans for actuating the lever 36, and the edge 46 forming the drop orrelease edge of each cam projection. Four of the cam projections areshown by Fig. V arranged at regular intervals to operate with theoscillating lever 36, and said projections are so disposed in connectionwith the controller or ily wheel 42 that they will engage the roller 39and oscillate the lever 36 immediately after the wings 12 have passedover the exhaust openings 20, and form with the said wings completepockets with which the ingress ports 19 centrally communicate asparticularly shown by Fig. III. The oscillating lever 36 operatesagainst the resistance of a retractile spring 48 secured to the 105outer edge thereto, adjacent to the point or attachment thereto of thepull lever 41'and also to the head 3. This spring 48 operates to restorethe lever 36, and parts combining therewith, to normal position when theroller 110 39 clears the edge 45 and apex 47 of each cam projection 44.

The operation of the actuating means and controller is very simple butat the same time positive. When the lever' 36 is oscil- 115 lated byeither of the cam projections 44 the upper extremity 38 thereto isthrown inwardly and the lower extremity is moved out against theresistance of the spring 48 and exerts a drawing force on the pull lever41 120 from the time that the roller 39 starts from the base of the edge45 of each cam projection until said roller clears the projection. Thisdrawing` action set up with respect to the lever 41 is transmitted tothe ring 33 and 125 the latter, through the pockets 34 rotates thesleeve 15 and the closers or walls 16 in the direction of rotation ofthe shaft 8 and the wings 12, and the parts are so proportioned thatjust as the roller 39 clears each 130 walls 16 will occupy properpositions with i relations to the previously advancing wings 12. Themovement of the closers or walls 16 also sets up a corresponding`rotation of 1 the cylinder 7 in view of the fact that the I' saidclosers or walls are secured to the cylinder as hereinbefore explained,and in order to prevent this cylinder from having back movement, it isprovided at intervals with notches 4Q to receive dogs 50, held at thecenter of the inclosure 2, within housings 51, as clearly shown by Figs.H and 1H. The dogs 50 are continually pressed by springs 52 which holdsaid dogs in engagement with the notches 19, and as the cylinder 7 isrotated regularly with the closers or walls 16 the dogs 50 take into theseveral notches 49 which will be in position for engaging with the dogsat the time when the closers or walls 16 are adjacent or in relativepositions to the wings 12, or just when the pockets have beenrestablished.

Power may be taken from the shaft 8 by any suitable means, a band wheelor pulley 53 being shown for this purpose in Fig. l.

The motive agent, as hereinbefore indicated may either have expansivecharacteristic or be of a fluid nature, and move the wings 12 at thecorresponding' operating parts by pressure. 1t is preferred, however,that steam be used as the motive agent. Wlhatevei may be the nature ofthe motive agent the operation will be the same, as may be summarized asfollows: The entrance of the motive agent into the several pocketsbetween the Wings 12 and the closers or walls 16 cause the wings to moveaway in advance of the closers or walls until the exhaust ports oropenings 20 are passed, and during this movement of the wings theactuatingmeans, embodying the controller having the cam projections 4:4and the levers 36 and 41 and the ring 33 with the dogs 34, will be inposition for operation of the cam projection 411 at the time that willcome into service with respect to the roller 39 which will be ad vancingtoward the said roller, and almost instantly this actuating mechanismwill be set in operation to throw up the closers or walls 16 adjacent tothe advance wings. As this operation becomes rapid it is acceleratedproportionately to the increased speed of rotation of the shaft 8, andthen as the closers or walls 16 arrive in place the plug valves 21 willbe shifted or turned to open up communication between the supply and theingress ports 19, hence the several operations will regularly take placein sequence at proper intervals and the shaft 8 will have a continuousrotation imparted thereto.

The improved rotary engine or motor is exceptionally effective as adriving means, and economically, in the use of a motive agent shaft, inview of the removable or counteracting resistances to the said rotationof the shaft 8 and the reliability of the operation of the severalmechanisms in direct relation will be conducive to the generalefficiency of the engine or motor.
